‘Sticky’ or slow brake pad return feel/excessive lever throw
Before completely disassembling your caliper, it’s worth trying to loosen the sticky pistons. Try the following:
1.
Clamp the bicycle in a bicycle work stand.
2. Remove the affected wheel.
3. Squeeze the brake lever several times until the pads nearly contact one another.
4. Push the XO Trail pad spreader clip in between the pads to spread the pads to the full width of the clip.
5. Remove the clip.
6. Repeat steps 3-5 several times.
7. Reinstall the wheel.
8. Squeeze the lever several times to position the pads at the proper distance from the rotor.
9. Center the caliper on the rotor if necessary.
10. Spin the wheel and check brake function. All pistons should now be moving freely and there should not be excessive lever throw. If
there is no improvement, continue with caliper service.
